Part of the Super Knuckle system that features a sleeve that tightens and holds a ball accessory at each end, the Super Knuckle Ball with 5/8" Baby Pin from Kupo moves omnidirectionally in the optional sleeve and connects to items such as light fixtures with a 5/8" receiver. Adding an optional ball at the other end of the sleeve creates a mount with flexible positioning. Both ball accessories are tightened down simultaneously with a T-handle. The 1/4"-20 female thread on top of the Baby pin offers additional mounting options.
